近十余年来,在探讨作物产量形成的生理基础的问题时,引用了“源”(光合产物的供应)和“库”(光合产物的贮积)的观念,来分析它们对于产量形成中起的作用,以及根据源库关系来剖析作物丰产型的改良途径[1][2][3]。但是关于如何运用源库关系来调节或控制产量形成,从而给合理制定栽 In the past decade or so, the concept of “source” (supply of photosynthate) and “pool” (storage of photosynthate) have been used to explore the physiological basis for crop yield formation in order to analyze their impact on yield formation As well as to analyze the improved ways of high-yield crops based on source-sink relations [1] [2] [3]. But on how to use the source library relations to regulate or control the formation of yield, thus giving a reasonable planted
